Interaction Structures of the Universe This article is essentially a continuation of Systems Thinking: An Operational Perspective of the Universe in which the Reinforcing and Balancing structures were developed.

Archetypes - Interaction Structures of the Universe

This article develops a set of frequently recurring structures resulting from various combinations of Reinforcing and Balancing structures. This article essentially represents an elaboration of the work of Senge (1990) and Pegasus Communications (1989-1996). Note that all the archetype examples that were previously wired into this article are now accessible via theWay which is considered to provide a more comprehensive treatment of the archetypes, as well as a few additional ones, and uses the "+" and "-" influence notation.
